Stratovolcano A volcano may defined as an opening or a rapture in the planet 's surface that can allow hot magma , gases , and , ash to escape from under the surface . There are many types of volcanoes and these include lava domes , cryptodomes , volcanic cones , super volcanoes and stratovolcano A Stratovolcano which is sometimes called a composite volcano is a conical , tall volcano which has several layers (strata ) which are hardened tephra , lava , and volcanic ash . Stratovolcano is characterized by a steep a steep pro which has periodic explosive eruptions . The lava
flowing from stratovolcano appears to be viscous and this makes it to cool and becomes hard before spreading in to a large area . This lava is formed from felsic which has very high intermediate levels of silica which has a lesser amount of the less viscous mafic magma
In some cases , stratovolcanoes are referred to as composite volcanoes due to the presence of a composite layered structure which is built from the sequence of outpourings of the materials from eruption Stratovolcanoes are the most common volcanic activity which is a contrast to the less common shield volcanoes . The most famous stratovolcano is the Krakatoa which is best remembered for its eruption in 1883
Stratovolcanoes are mainly common in subduction zones , where they form chains along the tectonic plate boundaries where the continental plates are drawn over the oceanic crust or another oceanic plate . This results in to continental arc volcanism found in places such as Central Andes where we...
